编译服务器端源代码

注册：注册的过程中会生成BankImpl_Stub.class(用于拷贝至客户端);

启动服务器：

客户端代码：

Customer.java

public class Customer implements java.io.Serializable{
    private String name;
    private String email;
    public void setName(String name){
        this.name=name;
    }
    public void setEmail(String email){
        this.email=email;
    }
    public String getName(){
        return name;
    }
    public String getEmail(){
        return email;
    }
    public String toString(){
        return name+" "+email;
    }
} 

Bank.java

import java.rmi.*;
import java.util.*;
interface Bank extends Remote{
public List<Customer> getCustomers()throws RemoteException;
}  

MyCLient.java

import java.util.*;
import java.rmi.*;
public class MyClient{
public static void main(String args[])throws Exception{
    Bank b=(Bank)Naming.lookup("rmi://localhost:6666/mine");
    List<Customer> list=b.getCustomers();
        for(Customer c:list){
            System.out.println(c);
        }
        System.out.println("done");
    }
}  

编译：
